FDM 3d-printer simulator

tdp-tl is a 3D printer simulator which targets to simulate visual artifacts of FDM printing: layer lines, under/over extrusion marks, ringing/ghosting, infills, supports, etc.

Getting Started

cargo build --release

# generate obj models, from gcode layer by layer
tdp-tl gcode-layers --gcode demo/KK_xyzCalibration_cube.gcode --outdir gcode/

# render obj model to still image, with blender
find gcode/ -maxdepth 1 -type f -name '*.obj' \
    | xargs -n1 -P4 -I{} blender -b tdp.blend --background --python render.py -- {} "{}.png"

# convert still images to timelapse video
ffmpeg -framerate 24 -pattern_type glob -i 'gcode/render/*.png' -c:v libx264 -pix_fmt yuv420p timelapse.mp4

Limitations / TODO

model-generation

• Following parameters are hard-coded
  • layer height (0.2mm)
  • filament diamger (1.75mm)
  • voxel size (0.04mm)
• Tested with Ultimaker Cura slicer only.
• .obj model file could be very large, several gigabytes for 20mm calibration cube.

rendering

• bundled blender scene is optimized for 20mm calibration cube.
• requires large amount of memory for rendering.
